Communication Systems Written communication involves any type of interaction that makes use of the written word. Communication is a key to any endeavor involving more than one person.
The hearsay rule does not apply to a representation contained in a document recording a message that has been transmitted by electronic mail or Term electronic communication a fax, telegram, lettergram or telex so far as the representation is a representation as to: Although largely superseded by the Internet, both traditional electronic data interchange EDI  and application-centric EDI  are other forms of data transmission via computer.
As well, applications are now being developed that can record and log instant messaging. Increasingly common is electronic communication by means of mobile phones, especially text messaging or SMS.
It is also possible, though not quite so easily done, to use a mobile phone to forward an SMS to a computer, where it can be printed out.
At any rate, all devices that can receive an SMS can forward the message to another device. Electronic communication can also be by way of photos taken with a mobile phone camera, a device becoming increasingly popular.
An understanding of messaging technologies is required before a view can be formed about the suitability of the technical language used. The following paragraphs give a brief outline of the technical aspects of ethernet and telecommunications technology. These signals are generated as electromagnetic waves analogue signaling or as a sequence of voltage pulses digital signaling.
To be sent from one location to another, a signal must travel along a physical path. The physical path that is used to carry a signal between a signal transmitter and a signal receiver is called the transmission medium.
There are two types of transmission media: The atmosphere and outer space are examples of unguided media that are commonly used to carry signals. These media can carry such electromagnetic signals as microwave, infrared light waves, and radio waves. When transmitted through wire and cable, the signal is an electrical waveform.
When transmitted through fibre-optic cable, the signal is a light wave: Such devices are designed to propagate a particular type of signal across a particular type of transmission medium.
Transmitting and receiving devices used in computer networks include network adapters, repeaters, wiring concentrators, hubs, switches, and infrared, microwave, and other radio-band transmitters and receivers. A microwave transmitter uses the atmosphere or outer space as the transmission medium to send the signal to a microwave receiver.
The microwave receiver then either relays the signal to another microwave transmitter or translates the signal to some other form, such as digital impulses, and relays it by another suitable medium to its destination.
However, because they transmit light waves rather than radio waves, they require a line-of-sight transmission path. The personal area network PAN  takes advantage of the conductive powers of living tissue to transmit signals.
The PAN device, which can be worn on a belt, as a watch, or carried in a pocket, transmits extremely low-power signals less than 1 MHz through the body. With a handshake, users could, for example, exchange business cards. As highlighted by the discussion of the technology, ways of communicating electronically are expanding and changing rapidly.
The Commissions stated that a broad and flexible approach to this technology is needed.
A draft provision is included in Appendix 1. However, as a limitation is applied on the use of speech the definition of electronic communication is in two parts. This is intended to allow information in the form of speech to be included in the scope of the Bill only where the information is provided by a person in a form that is analogous to writing.
This provision is intended to maintain the existing distinction commonly made between oral communications and written communications. The intention is to prevent an electronic communication in the form of speech from satisfying a legal requirement for writing or production of information.
For example, it is not intended to have the effect that a writing requirement can be satisfied by a mere telephone call, message left on an answering machine or message left on voicemail.
For example, information may be in the form of text in a paper document but is then transferred in to the form of data in an electronic document.
Presumptions facilitating proof of electronic communications 6. The sections apply presumptions relating to the sending or transmission and receiving of these communications. Currently, the transmission and receipt of these must be strictly proved.
The CDPP observes that investigative agencies devote considerable resources to proving strictly that a person sent or received an email. The Commissions are confident that, had present-day electronic communications been as commonly in use at the time the Evidence Act Cth was drafted, a provision equivalent to s presumptions relating to telexes applying to electronic communications would have been included.
Accordingly, the Commissions recommend that the uniform Evidence Acts be amended to remedy this omission. The new section should be drafted to include presumptions as to the source and destination of the communication.
Recommendation 6—3 The uniform Evidence Acts should be amended by the insertion of a new provision in terms equivalent to s facilitating proof of electronic communications. The provision will provide for presumptions in relation to electronic communications and should include presumptions as to the source and destination of the communication.e-mail; electronic mail; email ((computer science) a system of world-wide electronic communication in which a computer user can compose a message at one terminal that is generated at the recipient's terminal when he logs in).
"electronic communication" means the transmission of information, data, or a communication by the use of a computer or any other electronic means that is sent to a person and that is received by the person.
